How to Render with Frontface Culling
Applying this node set up (in Blender Render) will cull frontfaces. Apply your texture in the texture box onto the material you want to use. Linking it with color. Set the material to color output. Add a geometry node and set that to alpha. You need to set this to anything that has a mesh within it. But you will not need this setup for the most center mesh. For the most center mesh you can just apply whatever material/texture you want as typical with or without the nodes.
